Comprehensive Evaluation of Growth and Reproductive Traits of Different Strains of Neopyropia yezoensis
摘要
Abstract
In order to screen for Neopyropia yezoensis with excellent growth and reproductive traits,this study analyzed the growth and reproductive traits of shell-boring conchocelis and thallus across 13 cultivated strains of N.yezoensis.The results showed that there were differences in the same trait among different strains.Among them,the length growth rate of shell-boring conchocelis(CLGR)exhibited the smallest coefficient of variation of 21.62％,and the daily release of conchospores(DAR)showed the largest coefficient of variation of 172.69％.Correlation analysis of traits across two generations of N.yezoensis demonstrated a significant positive correlation among DAR,thallus length growth rate(TLGR),and width growth rate(TWGR).Cluster analysis identified three strains(Y-9904,Y-2301,and Y-2201)of shell-boring conchocelis and one strain(Y-9904)of thallus with fast growth rate and strong reproductive ability.The consistency of traits between generations within the same strain was evaluated by comprehensive D value assessment.The Y-9904 strain exhibited fast growth and strong reproductive ability in both generations,with TLGR,TWGR,length-to-width growth rate(TL/WGR)and DAR exceeding those of other strains.This study establishes a comprehensive method for assessing the growth and reproductive traits of N.yezoensis,which can provide a theoretical basis for breeding high-quality N.yezoensis varieties.关键词
